Energy-saving valve for refrigeration equipment and application thereof

Abstract

The invention relates to an energy-saving valve for refrigeration equipment, and the energy-saving valve provided by the invention comprises a valve body, wherein two three-way channels are arranged in the valve body; a passage is communicated between the two three-way channels; the two three-way channels are both provided with two passages which are connected to the outside of the valve body; a T-type three-way valve is arranged in one of the three-way channel; one of the passages connected to the outside of the valve body of the three-way channel is a steam outlet pipe while the other passage is a connection pipe I; one of the passages connected to the outside of the valve body of the other three-way channel is a refrigerant filling nozzle while the other passage is a connection pipe II; and the refrigerant filling nozzle is provided with a one-way valve. The invention also relates to applications of the energy-saving valve in filling a refrigerant to the refrigeration equipment and detecting leakage in the refrigeration equipment. The energy-saving valve for the refrigeration equipment has the advantages that the structure is simple, the operation of filling the refrigerant into different refrigeration equipment or the operation of leakage detecting maintenance is realized by using the compressor of the refrigeration equipment, and the operation is quite convenient. The energy-saving valve for the refrigeration equipment is suitable for the refrigeration equipment such as a refrigerator, an ice tank, an air conditioner, and the like.

Description

technical field [0001] The invention relates to a refrigeration equipment accessory, and also relates to the application of the accessory in refrigeration equipment. Background technique [0002] Refrigeration equipment generally consists of a compressor, condenser, filter, capillary tube and evaporator to form a fully enclosed refrigeration system. Its working principle is that the compressor sucks the refrigerant that absorbs heat in the evaporator into a low-pressure and low-temperature gas into the compressor through the pipeline. , and compressed into high-pressure and high-temperature steam, and then discharged to the middle branch of the condenser, thereby continuously reducing the temperature in the refrigeration room. [0003] At present, the refrigerant is usually added from the process pipe of the compressor to the shut-off valve equipped with a pressure gauge for vacuuming, and then the refrigerant is added. In this way, another compressor or vacuum pump must be ...

AI Technical Summary

Problems solved by technology

At this time, it is still impossible to tell which parts in the condenser, filter or evaporator have leaks, and only roughly know that there are leaks in some parts of the system, which will bring great trouble to leak detection and repair.
